The tail of Halley ’s Comet will “hit” the Earth in some days. What we will see in the sky
The Eta Aquarids can be a spectacular meteor shower. It peaks each year around early May and in the case of this year’s shower, the peak is expected in the morning of May 6, but meteors from this shower can be seen between April 19 and May 28, runs Discovery News.
Meteors can be seen when the Earth plows through the orbit of Halley’s Comet which means they are related to the Orionids shower in October, whose members are also the remnants of the same comet. The visibility of the shower tends to be a little better for observers around tropical and southern latitudes, but the Eta Aquarids can be seen further into the Northern Hemisphere and a good display can still be enjoyed.

At any given time, the radiant for the Eta Aquarids (or any other point in the sky for that matter) rises at the same local time for one location as it does for any other location. However, sunrise happens a little later in the southern hemisphere during May than it does in the northern hemisphere. This means that Aquarius has risen higher in the pre-dawn sky giving Southern Hemisphere observers a better chance of seeing meteors from this shower.
 
The comet's periodicity was first determined in 1705 by English astronomer Edmond Halley after whom it is now named.
 
During its 1986 apparition, Halley's Comet became the first to be observed in detail by spacecraft,  providing the first observational data on the structure of a comet nucleus and the mechanism of coma and tail formation.

Carmelia Albu – Ombudsman of the Public Broadcaster „Teleradio-Moldova”, in the service of community

Ombudsman service is an independent source of information, explanation and analysis of the Public Broadcaster’s programs and adherence to European standards and practices of broadcasting programs’ development.

Ombudsman is a mediator who handles complaints between a televiewer /radio-listener or a group of people and the Broadcaster. Ombudsman replies to the questions of TV viewers and Radio-listeners, receives and reviews complaints from people.

“Ombudsman” was first used in its modern sense in 1809 when the Swedish Parliament established the office of Justitieombudsman, who was to look after citizens’ interests in their dealings with government.

Later, in 1988, a similar service was established in media in France. It was a real "explosion” that caused the appearance of similar services in other world countries.
